Missing the timing

If you take damage in the middle of a chain, then you cannot activate the effect of "Gorz the Emissary of Darkness". Its effect cannot interrupt the resolution of a chain, and after the chain resolves, you have missed the timing to activate the effect.[8]

Previously Official Rulings

These TCG rulings were issued by Upper Deck Entertainment and have since been deemed unofficial by Konami.[21] They were previously considered official and can still be correct, as long as they follow the official gameplay rules, or unless Konami has issued a ruling that says otherwise.
